Installing an RE Module in an EX9200 Switch
The Routing Engine module (RE module) in an EX9200 switch is a hot-insertable and
hot-removable field-replaceable unit (FRU); You can remove and replace it while the
switch is running without turning off power to the switch or disrupting switching functions.
Each RE module is installed horizontally in a Switch Fabric module (SF module) installed
in the switch.
CAUTION: Do not lift the RE module by holding the ejector handles. The
ejector handles cannot support the weight of the module. Lifting the ejector
handles by the levers might bend the levers, and the bent ejector handles
will prevent the RE module from being properly seated in the chassis.
Before you begin installing an RE module in an EX9200 switch:
•
Ensure you understand how to prevent electrostatic discharge (ESD) damage. See
“Prevention of Electrostatic Discharge Damage” on page 351.
Ensure that you have the following parts and tools available to install an RE module:
•
ESD grounding strap
•
Phillips (+) screwdrivers, number 1 and 2
To install an RE module in an EX9200 switch:
1. Attach the ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2. Taking care not to touch the leads, pins, or solder connections, pull the RE module
out from the bag.
3. Ensure that the ejector handles are not in the locked position. If necessary, flip the
ejector handles outward.
